Both approaches share the goal of finding causal dependencies between a hazard on system level and failures of individual components. Qualitative approaches focus on the question “What must go wrong, such that a system hazard may occur? The complexity of the technical systems such as Improvements of Design and Materials, Planned Inspections, Fool-proof design, and Backup Redundancy decreases risk and increases the cost. Traditionally, safety analysis techniques rely solely on skill and expertise of the safety engineer.
In the last decade model-based approaches have become prominent. In contrast to traditional methods, model-based techniques try to derive relationships between causes and consequences from some sort of model of the system. Reactor Safety Study or the Rasmussen Report. This quantiazation is difficult for software —a bug exists or not, and the failure models used for hardware components do not apply. Failure modes with identical effects can be combined and summarized in a Failure Mode Effects Summary.
